Chris Brown Quits Twitter

Chris Brown's sound off against music retailers may have gotten him in some hot water. Just days after tweeting about how stores were "blackballing" his CD and not carrying it, Chris' account @mechanicaldummy was deleted. "Wanna thank my fans for all your support. I love y'all, goodbye" Chris tweeted.

Chris came out against Wal-Mart the hardest. The retailer fired back, saying they were in fact selling his latest CD "Graffiti".
